Hioki 3129 Field Measuring Instrument Phase Detector for Thin Conductors is a phase detection (positive and negative) field measuring instrument that uses the electrostatic induction method for voltage detection. Made specifically for thin conductors, the clamp diameter opens from 2.4 to 17mm. With a voltage range of 70 to 600VAC, this non-contact phase rotation meter is useful for a wide range of applications. Phase indication uses a series of 4 LED lights in combination with different beeping sounds for positive and negative detection. The compact size of the unit makes it easy to store and use. Carrying case and a wrist strap are included for added convenience.

Features:• No metallic exposure ensures absolutely safety to the operator• Wide clips compatible to thick cables of up to 40mm in diameter
